Split-extended LDPC codes for coded cooperation

  title={Split-extended LDPC codes for coded cooperation},
  author={Valentin Savin},
  journal={2010 International Symposium On Information Theory & Its Applications},
We propose a new code design that aims to distribute an LDPC code over a relay channel. It is based on a split-and-extend approach, which allows the relay to split the set of bits connected to some parity-check of the LDPC code into two or several subsets. Subsequently, the sums of bits within each subset are used in a repeat-accumulate manner in order to generate extra bits sent from the relay toward the destination. We show that the proposed design yields LDPC codes with enhanced correction… CONTINUE READING
